From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is a TUI? I haven't heard that term before.
ncurses and similar. Think 1980s word processor, emacs, vi, Slackware installer, etc.
Slackware was my first linux back in the day. :)
Emacs is actually a real GUI application. It has font sizes, variable width fonts, image display, etc. and with the pGTK backend even native wayland support. It also has a rendering backend for the terminal, and some people have their reasons for using it, but the default and general advice is to use Emacs in GUI mode.
